PURPOSE:To provide a polyester composite film for laminating metal which has excellent heat resistance, defomtation resistance, impact resistance and adhesive properties and in which no wrinkle occurs even at the time of heat treating. CONSTITUTION:A polyester composite' film for laminating metal comprises a laminated structure of an A layer, a B layer, a C layer and a D layer, wherein the A layer is made of polyester having a crystallization temperature Tc2 is 150 deg.C or higher, the B layer is formed of polyester having a melting point Tm of 190-225 deg.C and a glass transition temperature Tg of 50 deg.C or higher, and the C layer is formed of polyester having Tg of 30-50 deg.C. |
